Hi Technic folks. I need some help with a practical application to which I'm
trying to apply a Lego solution. The lights in my new office are
motion-activated - no way to turn them on all the time - and the detector is
behind my monitor! So I thought I'd build me a waving-machine, windmill or the
like, to keep the lights on. However, all the power sources I know of take
batteries, except the Control Centre, which I think is overkill and I wouldn't
want to tie mine up permanently. How can I get an ordinary motor to run on AC
power? Thanks for any advice!
Cheers, Heather
